        3. Test the look and field a bit more (especially the
           different wizard styles, and how they interact with
           pixmaps, titles, subtitles, etc.).

        4. Test minimum sizes, sizes, maximum sizes, resizing, etc.

        5. Try setting various options and wizard styles in various
           orders and check that the results are the same every time,
           no matter the order in which the properties were set.

           -> Initial version done (tst_QWizard::combinations())
